we are thinking how are we going to be able to track the users that only "see" an experiment
meaning, a user lands on a page, gets allocated to 'B' but doesn't do anything else, how will growthbook know this user was part of the experiment?

07/04/2022, 12:06 PMWhen you track experiment you are making a db connection between userId - experiment id and variation, so even if user doesn’t see anything it’s being counted
in order to facilitate that don’t miss the tracking mechanism from SDK

yes, after allocation we fire the trackingCallback function where we pass the experiment, user id, and variation
it is up to you to track that event to your data warehouse using whatever event tracking system you like
(if you don't have any event tracking setup, we can recommend some)

Something that will allow us to look at funnel/segments by experiment
